Hi,

I am switching from Infinitime to WaspOS.
I have flashed the bootloader using Gadgetbridge (GB).

Now I am unable to flash micropython.zip.

1. I have tried to flash it by connecting GB to unsupported device PineDFU, but then when flashing the file I get: "Element could not be installed". I tried following this other issue with a similar problem
   but no renaming of the file worked for me, GB File Installer still refuses to install micropython.zip.

2. I have tried connection from linux:
   wasp-os-0.4.1>$ ./tools/ota-dfu/dfu.py -z build-pinetime/micropython.zip -a DC:6F:70:63:E9:F7 --legacy
   But get the following output:

wasp-os-0.4.1>$ ./tools/ota-dfu/dfu.py -z build-pinetime/micropython.zip -a DC:6F:70:63:E9:F7 --legacy
Sending file firmware.bin to DC:6F:70:63:E9:F7

Waiting for Image Size notification
Waiting for INIT DFU notification
Exception at line 166: a bytes-like object is required, not 'str'

Line 166 is ble_dfu.start().

The watch is successfully in OTA update mode, and the bluetooth icon in bottom right goes blue when running the command, but then the error occurs and nothing more happens.

Pinetime was previously running custom Infinitime build with the 1.0.0 bootloader, and is a sealed device.

Any suggestions are welcome !
